As the solar energy warms the chip, so thermionic emission of electrons also contributes to the power generated, adding to the efficiency of the device.

Narrowband transmission uses radio signals that see flat fading. The channel may be considered relatively constant over the transmit bandwidth. This criterion is found to be satisfied if the transmission bandwidth does not substantially exceed the 'coherence' bandwidth Bc of the channel. This is the bandwidth over which the channel transfer function remains virtually constant.
